To all whomit may concern." i Be dtknownthat I, WALTER ALLEN STEWART, ofthetownof Smiths Falls, in the county of Lanarkyin the Province ofOntario, Canada, have invented certain new and useful Improvements inDevicesfor Preventing the Creeping of Railway-Rails, of which thefollowing is the" specification. My invention relates to improvements indevices for preventing the creeping of railway rails and the object ofthe invention is to: devise a simple device which may be readily andquickly placed in position in en gagement with the rail so as toabsolutely prevent it creeping longitudinally and it consistsessentially of the following arrangement and construction of partsasherenr after more particularly explained. "Figure 1, is a perspectiveview of my device showingit applied toe portion of a railway rail and aportion of the sleeper supporting the rail. i F Fig. 2, is alongitudinal section through 1g.1. i Fig. 3, isa cross section on line:0- y,

they are connected together by the bridge 3 are extended upwardly inhook form at 3",

the hook portions 3 being webbed together at 3 so as toform a keyreceiving orifice 3 At the upper end of the hook portion 3 a hookextension 3 is formed, such hook portions being connected together bythe extensionof the web 3 In the center of the portions?) and 3 arerecesses8 andS extending into the upper edge of such portions 8 -and 3.The bottom of each of the recesses 3 and3 at the end of each recessadjacent to the hook portion 8 is downwardly inclined to conform withthe incline of the portion 3 4-indicates a bracket provided with averticalportion P adapted to bear against the vertical face of thesleeper 2 and a horizontal portion 4 which extends through the recesses3 and 3 The vertical portion 4P of the bracket 4 is provided with avertical slot 4, the outer vertical edges of which areflared outwardlyas clearly shown in Fig. 4.: Thetongue 3 extending from the portion 3passes through the major portion of the slot ythe outer extremity of thetongue being riveted out or spread into the flared P01131011 of the slotso as to prevent its withdrawal. The verticalwidth of the tongue 3 isless than the length of the vertical slot l] and, therefore, allows of arelatively vertical movement between the bracket 4 and the'holder 3. Theupper face of thehorizontal portion 4 is provided with a rectangularrecess 4 in which fits a hardened metal plate 5 providedon its. upperface with a plurality of triangularribs 5 so as to form a grippinesurface. The hardened plate 5 is held within the recess 4 by havingsmall portions 4 intheside edges of the recess swaged over so as toextend over the edge of the hardened plate 5. i

6' indicates a tapered key which passes throughthe key receiving orifice3 and longitudinallybetween the portions 3* and 3 of the holder 3, thelower edge of the key bearthe side portions 3* and 3 are connected together by the bridging portion 3 By this means this end of the portion 3is reinforced for a purpose which will hereinafter appear.

The ends of the portions 8* and 3 where ingupon the bridging portions 3and 3 and the upper edge of the key bearing against the lower face ofthe horizontal portion 4! of the bracket 4. c

When it is desired to place my device in position so as to secure therail all that it is necessary to do is to move sufiicient gravel fromunder the railadjacent to the rail sleeper, then insert the holder 3beneath the rail'so'that the edge l of the'fiange 1 of the rail entersinto the hook portionsfi", the holder 3 then being in an inclinedposition relative to the rail'orwithithe portions? parallel with thelower face of the rail. The opposite end of the holder is then lifted upso that the hook 3* is brought into a, position to engage with the edge1 of the flange l".

The holder-is then moved crosswise of the railso'that the flange edge 1-enters the hook 3 'andthe flange edgel into the-hook-B". The key 6 isthen inserted into the holder by 1 passing a through the orifice 3 andbetween the horizontal portion 4 of-the bracket land the bridgingportions 3 and 3. When the device is in this positio-n theverticalportion 4* of the bracket 4 bears against'th'eadj acent verticalface of the sleeper Qiand is thereby held from longitudinal movement inrelation to the rail in one direction. When in this position thekey 6 isdriven, forcing the bracket 4: upwardly and the gripping surface of theupper face of the bracket, into engagement with the lower faceofitherail flange 1*. By this means the rail is held definitely in placefrom longitudinal movement inone direction. A similar device may beplaced on the opposite side of the'sleeper and engaging the rail so asto prevent longitudinal movement of the rail in the opposite direction.a

7 My device'is preferably made of malleable iron with the exception ofthe inserted plate 5, which necessarily must be of hard metal in orderto form a grippingsurface engag ing the rail flange. It will'be readilyseen that my device forms a positivemeans for preventing the railcreeping and when onoe applied will never crack or jar-loose owing tothe use of the malleable iron key which, when driven into place,'forcesupthe- 'hardened metal portion againstthebottom of the steel rail, thehooked ends of the holder by the same operation beingforoedintoengagement with the edges of the rail flange.

To'remove the device all that it is necessary to do is to drive out thekey'and the device may be readily removed from the-rail.

. -What I claim as my invention is.

1. In a device'for preventing the creeping of railway rails,- a holdermember having a key receiving channel extending longitudinallytherethrough and having-hook members at each'end adapted to engage theedges of the base flange of a rail, a movable member adapted to beinserted between the base flange ofthe rail and the holder between thehook portions thereof, and a key adapted to be driven longitudinally"through the holder "againstthe'"lower'face' of the movable mem-,wardly'from the hook orti-on at theend of the-inclined portion 0 the-holde'r,-a-movable member comprising --a vertical portion adapted tobearf'against the vertical face of a sleeperand ahorizontal portionadapted to extend between-the base of the rail and the holder andhavingits upper face formed with a rail gripping surface, and a key adapted toextend longitudinally 1 through the holder beneath the horizontalportionof such-member so as to "force it into engagement with the rail.

In a device for. preventing the creeping of railway rails, a holderadapted to engage the base flange of a rail, a pIOJGCtlOH QXtGIKL ingoutwardly from one face of the holder, movable'member extending betweenthe holder and'the lower face ofthe base flange of the rail and having avertical slot into which the-projection extends and is riveted to havefree vertical movement within the slot-such movable member being adaptedto bear against the rail supporting sleeper and having its-upperfaceformed with gripping surface, and means extending into the holderbetween the holder andthe 'movable memberfor forcing such movablememberintocontact with the rail. g

4. In a device for preventing the creeping of railway-rails, a holderadapted to engage the base flange of-a'raiha movable memberextendingbetween the holder and the lower face of the baseflange of therail and adapted to bear-against the rail supporting means and toengagethe lowerface of the rail, and

means-extending into the holder between the holder and movable memberfor forcing such member into the engaged position with the rail.
